Its approximate planting time is when other vegetables are planted that year, which is the best season to plant it, that is, to plant the best in spring
It prefers cool weather, so it doesn't have too high requirement for temperature. It can grow well at 5 to 35 degrees. It has very strong adaptability, but the temperature is the best between 10 and 25 degrees. In addition, if the temperature exceeds 30 degrees, it will go to sleep. When the temperature is lower than 0 ℃, its branches will wither. At this time, its tubers can be dug out and buried in sand and replanted next year.
It likes light very much, so it has to choose a place with a long time of light for planting. At the same time, it is not drought resistant and afraid of wetting. In the south, there is always more rain, so when choosing to plant, it must choose loose, well drained sandy soil.
If we plant it in the way of plant division, we should first take out its massive roots from March to April every year, and then separate the roots, and each root should have 2 to 4 apical buds, otherwise there is no way to grow new plants. After that, apply the plant ash on the root to help the wound heal. Finally, plant it and water it, so that the buds will grow in about a week.
First look for the side branch to be removed, let the branch keep at least three sections. When cutting, let two sections stay underground, and the other section stay on the ground. At the same time, after cutting, make sure that the soil is moist and the air is moist, so that it can take root as soon as possible.
When the seeds are collected in autumn, they can be sown from March to April next year. After planting, they should be covered with a thin layer of soil, then watered, and sprouted in about a week. At this time, they must be protected from strong light.
